自适应光学仿真软件，希望对大家由帮助！我还没有弄明白原理，希望一起学习(Adaptive optics simulation software, I hope all of you by the help! I have not understood the principle, I hope to learn)

说明：  滤波是将信号中特定波段频率滤除的操作，是抑制和防止干扰的一项重要措施，滤波分为经典滤波和现代滤波。(Filtering is the operation of filtering out the specific band frequency of the signal, which is an important measure to suppress and prevent interference. Filtering is divided into classical filtering and modern filtering.)

细节增强的直方图均衡法，在增强图像对比度的同时还能保留细节细心，避免了细节吞噬现象(Detail enhancement, histogram equalization, but also retained the same time enhance the image contrast details carefully, to avoid the details of phagocytosis)

用于分别从四个方向提取图形图像的纹理特征(For texture feature graphic images were extracted four directions)

用于图像去噪的代码，有模型去噪、双树复小波去噪，希望有帮助。(Code for image denoising, a denoising model dual tree complex wavelet denoising, hope to have help。)

Walsh变换在图像处理是一种非常重要的工具，在图像处理中和radon变换和hough变换都是非常重要的(Walsh transform in image processing is a very important tool, in Image Processing and radon transform and hough transform is very important)

干涉SAR图像配准程序，matlab编的，很好用！(Interferometric SAR image registration procedures, matlab, and easy to use!)

压缩传感，MATLAB，信号重建，正交匹配追踪，打破乃奎斯特定理(Compressed sensing, MATLAB, signal reconstruction, orthogonal matching pursuit, breaking the Nyquist Theorem)

sift特征提取，包括三部分，特征点提取，特征点描述，特征点匹配(sift feature extraction consists of three parts, feature extraction, feature point description, feature point matching.)

DCT数字水印基于CVI平台。用c编写的。(DCT digital watermarking)
